However, Porto president Pinto da Costa said he was confident the 18-year-old would stay, suggesting he could even follow in the footsteps of former Portugal defender Joao Pinto, who spent his entire career at the Estadio do Dragao.

"I hope that he stays for many years at FC Porto," he said. "Ruben has a contract until 2019 and not until 2017, as I have sometimes seen written, and we would like to keep him at the club, as a kind of Joao Pinto -- he was a symbol of the club's progress for generations.

Neves became the youngest player to captain a side in Champions League history in Tuesday's 2-0 victory over Maccabi Tel-Aviv and the Porto chief added that it was a "great satisfaction" to see him break the record.
